The case of a little boy stabbed more than 20 times while walking home from school shocked, saddened and angered people all over Houston. Vigils, marches and meetings were held demanding justice for 11-year-old Josue Flores.

Here's a timeline in this heartbreaking case:

"Rather than risk double jeopardy by trying to go to trial in a case where the evidence is too weak and then be forever barred from going after him or anybody else, for practical purposes, it is our decision to dismiss the charges and release the man from jail," said Tom Berg with the Harris County District Attorney's Office. They say Jackson is still a suspect in the case.
